Abstract
We present detailed design of a highly nonlinear chalcogenide core tellurite
cladding composite microstructured fiber and dispersion tailoring in it. The fabrication
procedure for the microstructured fiber is explained. Its applications to nonlinear
phenomena are described with the experimental demonstration of the supercontinuum
generation and the simulation of the parametric gain. It is observed that a
supercontinuum spectrum of 20 dB bandwidth covering 0.80–2.40 µm is generated by
this composite microstructure fiber when 1.85 µm pump is used. The simulation
results show that the bandwidth over which the calculated parametric gain is more than
10 dB is 1680 nm, ranging from 1.04 to 2.72 µm.
